［摘要］我国是一个地震频度高、强度大、震害分布广、震灾极为严重的国家，也是世界上地震灾害最为严重的国家之一。如何防范地震风险、有效降低震害损失成为我国面临的一项长期而艰巨的社会问题。而正确、合理地分析各类建筑物的抗震性能，提高建筑物的抗震能力是减少经济损失的有效途径。本文对已有资料及文献中的各类结构试验分析数据进行统计，并对其进行分类和归纳总结，最后利用MATLAB软件进行结构地震易损性曲线拟合，得到其地震易损性曲线，从而得出结构的整体破坏概率，为后期的地震保险工作积累数据。

Abstract：China is one of the countries where happened earthquake most serious in the world. The earthquake in China has those features: frequency, intensity, distribution of earthquake damage. How to prevent the earthquake hazards and effectively reduce the loss of damage becomes a long-term and hard social problem. An effective way to reduce economic losses is to find a correct and reasonable method to analyze the seismic performance of buildings and improve the seismic capacity of buildings. In this paper, the statistical data are from the other studies. It concludes the software simulation and shaking table test. Finally, the author uses the MATLAB software to get the seismic vulnerability curve of the buildings. From the curve, people can see the overall failure probability of structures. This also lays the foundation for the future earthquake insurance.
